QuestionQ34

Troubleshoot the wired network solution

You are implementing a design in which the campus network must use a spanning-tree topology isolated from the data center network. The core switches are connected through a single Layer 2 interface that carries multiple VLANs.

When you inspect the switches, you find that the campus core regards the data center core as the root bridge.

Which configuration can you apply to the campus-to-data-center core link to resolve this issue?

Explanation

Root Guard enforces the intended placement of the spanning-tree root by preventing the protected interface from becoming a root port. If the interconnecting link receives superior BPDUs from the data center core, Root Guard places the port in a root-inconsistent state rather than allowing the data center core to become the campus spanning-tree root.
